I just want to be able to run the numerical model on the other platform, not to have the same results.

I don't want to achieve reproducability, I just want a binary that runs on that platform. I don't expect a chaotic model to give the same results, for example. > It seems to me that the use case doesn't justify what you're asking > for though.

At least for me binaries linked on fedora may be run on centos4 with a different set of libraries/compilers. > someone is hell bent on producing statically linked binaries, then > they can download the source for the libraries they need and build and > link statically against them. Of course, but it would be way better for them if we could help them. -- Pat -- Fedora-packaging mailing list Fedora-packaging@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-packaging
